I-Cellulose Ethers kunye nokusetyenziswa kwazo
I-cellulose ethers yintsapho yeepolymers ezinyibilikayo zamanzi eziphuma kwi-cellulose, eyona nxalenye yesakhiwo seendonga zesityalo. Ezi ziphuma ziveliswa ngokuguqulwa kweekhemikhali zeselulosi, ukwazisa amaqela ahlukeneyo e-ether ukuphucula iimpawu zabo zokusebenza. Ezona zixhaphakileyo i-cellulose ethers ziquka iHydroxypropyl Methylcellulose (HPMC), Carboxymethyl Cellulose (CMC), Hydroxyethyl Cellulose (HEC),I-Methyl Cellulose(MC), kunye ne-Ethyl Cellulose (EC). Nazi ezinye zezinto eziphambili zokusetyenziswa kwazo kumashishini ahlukeneyo:
1. Ushishino loKwakha:
- I-HPMC (Hydroxypropyl Methylcellulose):
- Izinto zokuncamathelisa iithayile:Ukuphucula ukugcinwa kwamanzi, ukusebenza, kunye nokubambelela.
- Udaka kunye nonikezelo:Yandisa ukugcinwa kwamanzi, ukusebenza kakuhle, kwaye inika ixesha elingcono lokuvula.
- I-HEC (i-Hydroxyethyl Cellulose):
- Iipeyinti kunye neeNqaku:Isebenza njenge-thickener, ibonelela ngolawulo lwe-viscosity ekubunjweni kwamanzi.
- MC (Methyl Cellulose):
- Udaka kunye neePlasta:Yandisa ukugcinwa kwamanzi kunye nokusebenza kwizicelo ezisekelwe kwisamente.
2. Amachiza:
- I-HPMC kunye ne-MC:
- Ulwakhiwo lweCwecwe:Isetyenziswe njengezibophelelo, i-disintegrants, kunye ne-controlled-release agents kwiipilisi zamachiza.
3. Ishishini lokutya:
- I-CMC (iCarboxymethyl Cellulose):
- I-Thickener kunye ne-Stabilizer:Isetyenziswe kwiimveliso ezahlukeneyo zokutya ukubonelela nge-viscosity, ukuphucula ukuthungwa, kunye nokuzinzisa i-emulsions.
4. Iingubo kunye neepeyinti:
- HEC:
- Iipeyinti kunye neeNqaku:Isebenza njenge-thickener, stabilizer, kwaye ibonelela ngeempawu zokuqukuqela eziphuculweyo.
- EC (Ethyl Cellulose):
- Iingubo:Isetyenziselwa ukwenza ifilimu kwi-pharmaceutical and cosmetic cosmetology.
5. IiMveliso zokuKhathalela umntu:
- I-HEC kunye ne-HPMC:
- I-shampoos kunye ne-lotions:Yenza njengama-thickeners kunye nezinzisi kwiifom zokhathalelo lomntu.
6. Izinto ezincamathelayo:
- I-CMC kunye ne-HEC:
- Iindidi zokuncamathelisa:Ukuphucula i-viscosity, i-adhesion, kunye neempawu ze-rheological ekuqulunqweni kwe-adhesive.
7. Iimpahla:
- CMC:
- Ubungakanani beLaphu:Isebenza njenge-ejenti yokulinganisa, iphucula ukuncamathela kunye nokwakheka kwefilimu kwiilaphu.
8. Ishishini le-Oyile neGesi:
- CMC:
- Ulwelo loKwemba:Ibonelela ngolawulo lwe-rheological, ukunciphisa ilahleko yolwelo, kunye nokuthintelwa kwe-shale kwi-drilling fluid.
9. Umzi mveliso wamaphepha:
- CMC:
- Ukugqunywa kwePhepha kunye nobungakanani:Isetyenziselwa ukuphucula ukomelela kwephepha, ukuncamathela kokutyabeka, kunye nokulinganisa.
10. Ezinye izicelo:
- MC:
- Izicoci:Isetyenziselwa ukujiya kunye nokuzinzisa kwimixube ethile yesicoci.
- EC:
- Amachiza:Isetyenziswe kwimixube yeyeza elilawulwayo.
Ezi zicelo ziqaqambisa ukuguquguquka kwe-cellulose ethers kumashishini ahlukeneyo. I-ether ethile ye-cellulose ekhethiweyo ixhomekeke kwiipropati ezifunwayo kwisicelo esithile, njengokugcinwa kwamanzi, ukunamathela, ukuqina, kunye nokukwazi ukwenza ifilimu. Abavelisi bahlala benikezela ngamabakala ahlukeneyo kunye neentlobo zee-ether ze-cellulose ukuhlangabezana neemfuno ezahlukeneyo zamashishini ahlukeneyo kunye nemixube.
